“…the effect of regular exercise on mild to moderate forms of depression is similar to the effect of cognitive behavioral therapy, according to the co-authors of the book “Exercise for Mood and Anxiety,” Jasper Smits, associate professor of psychology at Southern Methodist University in Dallas, and Michael Otto, a psychologist at Boston University. The two authors analyzed the results of dozens of published population-based and clinical studies related to exercise and mental health to arrive at their findings.

There’s little consensus on how or why exercise helps, but Smits says the public health recommendation for daily exercise — 75 minutes a week of vigorous exercise or 150 minutes of moderate activity — should be more widely prescribed by mental-health care providers, especially as studies show that 25% to 40% of Americans don’t exercise at all. “Some professionals argue that exercise is the non-pharmacological antidepressant and may work in the same way as these medications,” he says.”
